Update:
My black and red ones were swapped out yesterday. The magnets hold the cap OK now and updating works just fine now as well.
IMPORTANT: If you cannot flash your
device - after the 17 finger acrobatic trick you have to perform - with a known good (!) cable -- you have no other choice then sending it back and get it replaced. (see my posts a couple of pages back)
BTW, you can change power in TC mode (fire + up button). The "power" mode is VW. In general the
device reads the resistance a bit on the low end, which of course means in TC mode the
vape is cooler than expected.
Cheers.
